The rotation'of the. transferrer 10 then forces the article across the suppo plate 25 until it engages the conveyer 7 in e position D illustrated in Fig. 1. Inasmuch as the conveyer 7 moves atA substantially one half the speed of the conve er 4 and the transferrer 10 the articles be deposited upon a transporting conveyer 7 in the staggered relation illustrated in the dra so that nearly twice as many articles will carried by the transporting conveyer as would be the case if the same were delivered successively in alinement upon the transporting conveyer.

By reason of this staggered relation. a given length of the transporting conveyer 7 carries a proximately twice as many articles as wouldp otherwise bedeposited upon it and as heretofore stated the speed of the trans porting conveyer through the drier is greatly reduced thus economizing in the use of these conveyers ywhich are of expensive construction and wear out quite rapidly.

In the molding of plates from machines of-the character above describedthe plate is usu-ally-deposited upon the p ,conveyer upside down and it is sometimes found desirable'to reverse its position during the first drying o eration. A convenient means of accomp ishing this purpose and at the same time preserving the advantages of this invention heretofore described is illustratedin F1g. 3 in which the transferring roller 10 is shown in a position to v deliver the articles upon an inclinedplate orchute 26, the lower end of which desirably is slightly upwardly curved and is adapted to de iver the articles, such as plates, right' side up upon the transporting conveyer 7.

In this construction aswell as in the one more fully explained the transferrin roller 10 may be reciprocated endwise, t at is, transversely of the direction of movement of the conveyers 4 and 7 so that the articles will be deposited in staggered relation in this embodiment of the invention as well as in the other.l

It is to be understood that the embodiment of the invention which is shown more or less diagrammatically herein is illustrative merely and not restrictive and that various modications in structure, form and relation of parts may be made the meaning and scope of the followin claims. Having thus descrlbed my inventlon what I claim asnew and desire to secure by Letters latent is: h
